android adb wireless

For some reasons, my phone does not work anymore with cable.

I saw on the Internet that it is possible to connect adb to the via Wifi, however I tried it and I get this:

adb devices
List of devices attached
192.168.1.2:5555        offline

I search this on Google and it seems that it is related to Android 4.2.2. And indeed, my device is running Android 4.2.2.

I didn't find any answers on Google for my problem since it is always with a cable, mine is on Wifi...

Any idea how to solve this?

Answer

For me the complete steps that worked were :

Settings -> Developer options -> Revoke USB debugging authorizations (clear the list of authorized PCs).
Set USB Debugging OFF.
In Terminal write : adb kill-server
Then : adb start-server
Then : adb connect xx.xx.xx.xx:5555 (the devices ip), it should say unable to connect.
Now turn ON USB debugging again and type the adb connect xx.xx.xx.xx:5555 again.

It should now ask for authorization and you are back online without needing to connect cable to USB, only wifi used.
